LUMBER-RULE.

Patented March 9, 1909.

' Application filed July 26, 1907, Serial No. 385,682. Renewed August 1,1908. Serial No. 446,410.

To all whom it may concern:

Be it known that we, JAMEs N. BRYANT and JAMES B. MCDON LD, citizens ofthe United States of America, residing at Nashville, in the county ofDavidson and State of Tennessee, have invented new and usefulImprovements in Lumber-Rules, of which the following is a specification.

This invention relates to lumber rules, and one of the principal objectsof the same is to provide a lumber rule made in sections and connectedtogether by hinged joints in order that the rule may be folded to occupybut small space in a traveling bag or other case.

Another object of the invention is to provide a lumber rule with ahinged joint pro vided with a removable pin so that the sections of therule may be locked rigidly in alinement or folded one section upon theother by removing the pin.

These and other objects may be attained by means of the constructionillustrated in the accompanying drawing, in which:

Figure 1 is a side elevation of alumber rule made in accordance with ourinvention, said rule being broken away at two points. Fig. 2 is an edgeview of the same, the rule being shown opened out. Fig. 3 is an edgeview of Fig. 4 is a sectional view of the rule joint, on the line 44 ofFig. 1.

Referring to the drawing for a more particular description of ourinvention, the numeral 1 designates the handle section of the rule, and2 is the head section thereof, 3 being'the head. It is to be understoodthat insofar as the general structure of the rule is concerned, it maybe of any desired construction or type, our invention residing wholly inthe hinging of the sections in order that the rule may be folded, forthe purpose described, and it will also be obvious that the rule may bemade in two, three or more sections, if desired.

The sections of the rule are connected together by hinges, the members 4of which are connected together upon one side of the rule by means of apermanent pintle 5 which maybe headed up at the end, as shown in Fig. 4.Disposed upon .the opposite side of the sections 1 and .2 the rulemembers 6 are detach-ably connected together by means of a taperingscrew or pin 7, said screw having a series of threads 8 at the endthereof which engage interior screw threads in the hinge members 6,while the opposite end of the screw is provided with a milled head 9 bymeans of which the screw may be readily de tached whenever it isrequired to fold the rule to the required length to be readily placedwithin a traveling bag or case.

From the foregoing it will be obvious that a rule made in accordancewith our invention can be quickly folded in position for shipping ortransportation, and that the various sections can be readily locked inalinement for use whenever required.

A rule made in accordance with our invention can be produced atcomparatively slight cost, and has been found very desirable for scalinglumber and logs by persons required to move about from place to place.

The numerals indicating the scale will be stamped on the hinges as wellas upon the sections of the rule, so as to permit the inspector to makerapid calculations. The hinges are to be of any desired length to securestrength.

Having thus described the invention, what we claim is:

1. A lumber rule made in sections and connected together by hingedmembers secured to opposite sides of said sections, one of said hingedmembers having a rigid pintle and the other hinged members having adetachable pin.

2. A lumber rule made in sections, said sections being connectedtogether by oppositely disposed hinged members, one pair of hingedmembers being connected together by a permanent pintle, and the oppositehinged members being connected by a tapering threaded pin or screwhaving a milled head.

In testimony whereof, we afiiX our signatures in presence of twowitnesses.
